Application meti April 4,

ffThe invention relates to plate assemblies,

. commonly known as plate thim'bles, devices of this character-beinglemployed to extend around pipes and Vcover openings in `'Hoor-s,

easily andinexpensively manufactured, mayV be applied .with ease and will be eiiicient and desirable'in use. f With the Aforegoinghin View, the invention J resides in the novel subject matter hereinafterdescribed and claimed,' the description by the laccon'ipanying drawings.`

Fig. lis an outer side elevation'ofa plate i p l lwhich are provided with the flanges 11 thinible y constructed in accordance. 'with this invention. y. 'Y Fig. 2 is a vertical sectional viewy on line 2 2 of Fig. 1. u l I Y' Fig. 3 isan inner slide eleyation. c Fig. 41 is a view similar to Fig. 3 but illustrating the plates swung apart for engageA ment with or disengagement fromr a pipe. Fig.- 5 is a transverse sectional view on line 5 5 of Fig.

Inthe drawingabove briefly described, 6

Y and 6a denote .two elongated metal plates having contacting longitudinalv edges 7 72, which edges are VJformedy with registering notches 8 8a jointly providing a receiving slot for a pipe P.. The other longitudinal edges of the plates 6 6a are formed with longitudinal flanges 9 9, said plates vare provided atone end with endr flanges 10 10?, and these plates have similar flanges 11 11"L at their opposite end. All of the flanges project laterally in the lsame direction from the plates as will be clear from the several views. 1

A metal strip 12 is disposed in the angle between the plates 6 6@1 and their end lianges 10 10a,said strip extending across -the line at which the edges 7 71 contact with each other, being secured to the plate 6 by rivets 13, by spot welding, Vor in any other desired manner, and being loosely pivoted .to the plate 6a. This kpivotal connection comprises a slot 14 in the strip .12, and a vrivet 15 passing through this slot and the plate 6a, said slot permitting necessary shifting of 1927. serial Naisoae."

the plate 6a towardor from vthe plate Gwhen applying, or removingv the` device,` as will; 4be hereinafter more `fullyV described.

The strip 12 is formed, inrits outeredge, with an angular notch 16, which notchjre-k ceivesthe inner end'of the flange 10*,"wh'en plate 6a is swung away from' plate 6,- as will. be clear from Fig. 4:. During this swinging, the inner'corn'er' 17 VVof plate 'ten'ds t0 tov crowd against the edge 7 of the. platel Gf'and would prevent relative openingof the two plates, were it not for theloosepivotal wconnectionV 14 15. This connection, however,

permits the corner 17 to move inwardlyv eral 4shifting of the plate 6a with respect to plate 6, permits relative swinging'off the 4two plates without hindrance.

For connecting the ends of Vthe plates 11a, I'provide a channel-,shaped metal strip 18 whose channel'permanentlyreceives the along the edge 17 and byallowing some lat-V flange 11a and is secured thereto by riveting,

'spot welding or 'the like. When the plates areV in ytheir closed positions, as seen vin Figs,`

1 and V3, the Ychannel-'ot` the; strip 18 also rel ceives Vthe flange 11'of the plate 6,'1'but`ina`y" Abe readily disengaged therefrom when the plates are to be swung into vtherelation shown in Fig. 11', when either applying or removing the device. Y Y

Screw holes 19 are formed in the outer corners of the plates 6 6a and when said plates are secured to a floor, wall or the like, by screws or nails passing through these holes, they are held in assembled relation as shown in Figs. 1 and 3.

y For' the purpose of sealing the slots 8 8, yet permitting shifting of the pipe P therein, I provide two relatively small plates 20 20L which contact with the inner sides of the plates 6 6a and are located within the coninesjof the flanges 9, 9a, 10, 10, l11 and 11a.v

keo

These smaller plates 2O 20'EL have notches i 21 21EL formed in their inner edges to receive the pipe P, and preferably, these plates are connected at one end in the manner shown, that is, by a strip 22 spot welded or otherwise secured to thek plate 20a as denoted at 2?,but pivoted to the plate 20 las indicated at 24.

i To slidably connect the two sets of plates,

I prefer to secure metal strips -25a to the Yinner sides of the plates 6 62, providing them with offset edge `portions which slidzibly engage the outer longitudinal edges o'l the plates 20`20. p p p Attention is now invited to Fig. 9.. From this View, it will be seen that the ends of the plates QO---QO7 carrying tlie'strip 2:2, are inwardly otl'set sutliciently from the plates 6--6, to clear the strip 1:2 and the "fasteners 13-15, when said plates 20m2()n niove toward said strip 12 to the maximum. p

Itwll be seen from the `foregoing that the invention is exeeptionally simple 1nd .inexpensive and is of such construction as to permit rapid and easy manufacture. Moreover, it 111e i be "quickly and easily applied, orire move with equal ease. On aeeoiint of these existing "advantages `for the `details disclosed, the ete by preference `followed. However, tvit in the scope ofthe iiivention es claimed, variations "may be inade.
